MOVED TO: https://github.com/cirosantilli/linux-kernel-module-cheat#userland-assembly SEE README. x86 IA-32 and x86-64 userland minimal examples tutorial. Hundreds of runnable asserts. Nice GDB setup. IO done with libc, so OS portable in theory. NASM and GAS covered. Tested in Ubuntu 18.04. Containers (ELF), linking, calling conventions.
